The Nakamura is one of the tradesmen's houses that have stood here since around 1600, when Tondabayashi Jinai-machi began to prosper. As is the case with the Old Sugiyama's Residence, which is the only house that visitors can enter, the Nakamura ran a sake brewery called Sado-ya and was one of the largest sake brewers in the Kawachi Province (the present neighborhood of Minami Kawachi-gun) around the 18th century. The document showing that Shoin Yoshida, one of the most distinguished intellectuals in the closing days of the Tokugawa shogunate, stayed for nearly one month and other famous people stayed there establishes how big Sado-ya was. The present residence is not the one from those days but was built around 1782, and is designated as an Osaka Prefectural Cultural Asset. This house is a valuable building with a style of merchant houses commonly seen in Osaka and Kyoto. Since it is a private residence, its interior is unfortunately not open to the public.
